C++ Qt 24 - QSlider and QProgressBar

[maxxemm]

Very clear and to the point explanation.

To make sure QObject::connect() works, I always use:

bool b = connect(...);

Q_ASSERT(b);

A warning note: don't use:

Q_ASSERT(connect(...));

as it will remove a call to connect() in release build.

is it possible to make the progress bar stay hidden unless a certain even occurs in which case it is no come into the main window?

@elperez1988 Go to slot(horizontal slider) valueChanged(int) and in there type  ui->lineEdit->setMaxLength(val­ue);
